User Summary A shoot em up game released as a download for the PSP. Choose from seven different planes, each with its own unique special attack, to battle your enemies. Enemy units mostly consist of WWII era planes, boats, and tanks but when enough damage is dealt to the boss of a stage it will transform into a powerful mechanized unit, giving the game a science fiction theme as well as a WWII era one. The game allows two people to play with the PSP Ad Hoc multiplayer.
